Abstract: Polarized 3D viewing systems inherently cut the viewing resolution in half. While 3D content looks of good quality, the quality of any co-existing 2D content in windowed mode on the same screen looks poor. Embodiments may be directed to modifying the 2D content in real time and presents the enhanced 2D content (i.e. 2D+) to each eye as if it was 3D content targeted at each of the left and right eyes separately. The 2D+ content quality thus appears much better than when viewing the original 2D content on a polarized screen through polarized eyewear.
